Grand Prix

There are three reversible motors that operate the Power Seat. The front and back heights of the seat are operated by different motors. It can be raised or lowered independently. When the Entire Seat Switch is pushed to the UP or DOWN position, both Height Motors run to move the front and back of the seat at the same time.

The Forward-Back Motor is operated by the Entire Seat Switch. When it is held in the BACK position, battery voltage is applied through the switch contacts to the LT GRN wire and the Forward-Back Motor. The motor is grounded through the TAN wire and the contact of the Back Switch to ground G304. The motor runs to drive the seat back until the switch is released.

In the FORWARD position, the TAN wire receives battery voltage and the LT GRN wire is grounded. This reversed polarity causes the motor to run in the opposite direction and drive the seat backward.

The Front and Rear Height Motors work in a similar way when the Front or Rear Height Switch is operated.

To raise the entire seat, the Entire Seat Switch is held in the UP position. This applies battery voltage to both the YEL and DK GRN wires. The LT BLU and DK BLU wires are grounded through both the Front and Rear Height Down and Entire Seat Down contacts to ground G304. Both motors run to drive the entire seat up. A similar action occurs to move the entire seat down.

Each motor contains a self-resetting circuit breaker to protect it from overload.
